“I did not kill my wife!” Ben Affleck‘s hubby protagonist Nick Dunne emphatically declares in the first trailer from the high-profile big-screen adaptation of Gillian Flynn’s worldwide bestseller Gone Girl. And though that catchphrase might be an echo from 1993′s The Fugitive, Dunne is a guy — unlike Harrison Ford’s Dr. Richard Kimble — who has the deck stacked against him when it comes to his murdered better half (Rosamund Pike). Or so it seems. One of Flynn’s inspirations for the novel stemmed from the psychology and dynamics of couples’ long-term relationships. CinemaCon attendees got an early look at the trailer last month. Fox will release the David Fincher film on the first Friday in October — in the same spot the director’s 2010 awards-season darling, The Social Network, launched. Neil Patrick Harris, Tyler Perry, Missi Pyle and Patrick Fugit round out the cast.
